first embodiment

[0024]FIG. 1 is a cross-sectional view of a fine bubble-containing liquid generating apparatus 1 according to the present invention. The fine bubble-containing liquid generating apparatus 1 is an apparatus for mixing gas and liquid to generate a liquid that contains fine bubbles of the liquid. In the following description, “fine bubbles” refers to bubbles with diameters of 100 μm or less, and “ultrafine bubbles” refers to fine bubbles with diameters of 1 μm or less. The “density” of fine bubbles refers to the number of fine bubbles per unit volume contained in the liquid.

[0025]The fine bubble-containing liquid generating apparatus 1 includes a generator 11, a circulation passage 12, an extraction part 13, a replenisher 14, a pump 15, and a drain part 16. The generator 11 includes a mixing nozzle 31, a pressurized-liquid generating tank 32, and a fine-bubble generating nozzle 2. The mixing nozzle 31 mixes liquid pumped by the pump 15 and gas flowing from a gas inlet and ejects a resu...

second embodiment

[0067]FIG. 7 is a cross-sectional view of a fine bubble-containing liquid generating apparatus 1a according to the present invention. The fine bubble-containing liquid generating apparatus 1a includes an initial circulation part 17, instead of the drain part 16 illustrated in FIG. 1. The other constituent elements are identical to those of the fine bubble-containing liquid generating apparatus 1 illustrated in FIG. 1, and the same constituent elements are given the same reference numerals in the following description.

[0068]The initial circulation part 17 includes a bypass passage 171, switching mechanisms 172a, 172b, and 172c such as valves, and an initial reservoir 173. One end of the bypass passage 171 is connected to the circulation passage 12 between the fine-bubble generating nozzle 2 and the switching mechanism 172c. The other end of the bypass passage 171 is connected to the circulation passage 12 between the switching mechanism 172c and the pump 15 on the downstream side of ...

Abstract

A fine bubble-containing liquid generating apparatus includes a generator including a mixing nozzle for leading in gas and pressurized liquid and a fine-bubble generating nozzle for discharging liquid that contains fine bubbles of the led-in gas, a circulation passage for returning liquid discharged from the fine-bubble generating nozzle to the mixing nozzle in a state in which the liquid is isolated from outside air, an extraction part for extracting, as a fine-bubble containing liquid, part of liquid circulating through the generator and the circulation passage, and a replenisher for replenishing the circulation passage with liquid to maintain the amount of liquid circulating through the generator and the circulation passage. With this configuration, it is possible to continuously generate a fine-bubble containing liquid that contains a high density of fine bubbles.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a 35 §§ 371 national phase conversion of PCT / JP2015 / 056185, filed Mar. 3, 2015, which claims priority to Japanese Patent Application No. 2014-058168, filed Mar. 20, 2014, the contents of both of which are incorporated herein by reference. The PCT International Application was published in the Japanese language.TECHNICAL FIELD[0002]The present invention relates to a fine bubble-containing liquid generating apparatus.BACKGROUND ART[0003]In recent years, liquids containing bubbles with diameters of 1 millimeter (mm) or less have been used in various fields. Also, liquids containing bubbles with diameters of 1 micrometer (μm) or less (ultrafine bubbles) have recently been gathering attention in various fields, and apparatuses for generating such liquids have been proposed.[0004]For example, in a fine-bubble generating apparatus disclosed in Japanese Patent Application Laid-Open No. 2008-272719 (Document 1), a gas-li...
